As the little alien explains to Sam, being invisible can be a big help. A very funny adventure story by award-winning author Sally Gardner, in her MAGICAL CHILDREN series.
When his parents are lost in space, Sam is left in the care of the horrible neighbour Hilda Hardbottom. There he finds a tiny spaceship in the cabbage patch and meets a little alien called Splodge. Splodge loves ketchup, enjoys learning languages and can make himself - and Sam - invisible. How Sam uses this helpful new skill is a very funny and satisfying story for young readers.
